Crossflow Blower Heater

Designed for maximum versatility, Tutco Farnam's Crossflow Blower Heaters (CB Series) feature multi-purpose mounting brackets that attach directly to the exhaust of a crossflow blower, eliminating the need for additional accessories. Additional mounting holes allow the heater to function independently as a stand-alone duct heater. Single and dual wattage, and/or dual voltage combinations are available. Integrated thermal fuses and/or hi-limit thermostats are available to provide over-temperature protection. Crossflow Blower Heaters are designed to meet your specific heating requirements. We match size, wattage, and voltage to meet your specifications for optimal system performance. Crossflow Blower Heaters are available in 5”, 7”, 10”, 12” and 15" standard lengths. Heaters are UL recognized components under UL file number E154979. These products are also commonly called:
- Crossflow or Cross-flow Fan Heaters
- Squirrel Cage Blower Heaters
- Tangential Blower Heaters
- Squirrel Cage Fan Heaters
- Tangential Fan Heaters
